Master Functions of the Liver fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• The major metabolic, regulatory and detoxification roles carried out by the liver.
• How the liver maintains stable blood glucose levels through glycogenesis and glycogenolysis.
• Formation of bile and the role of bile pigments produced from haemoglobin breakdown.
• How the liver detoxifies ammonia by converting it into urea in the ornithine cycle.
• The breakdown of ethanol and the role of NAD and enzyme systems in alcohol metabolism.
• How hepatocytes detoxify drugs and toxic substances using enzyme systems such as cytochrome P450.
• The role of catalase in breaking down hydrogen peroxide produced during metabolism.
